Skill Creator

If you're building skills for Claude, this is your starting point. It walks through the core tradeoffs: how to keep skills lean without bloating the context window, when to write instructions versus bundle scripts, and how to structure the three-level loading system (metadata, SKILL.md body, optional resources). The progressive disclosure patterns are especially useful if you're deciding whether to put everything in one file or split out references and assets. Think of it as the meta-skill that helps you avoid common mistakes like over-explaining what Claude already knows or creating extraneous documentation files that just add clutter.

About Skills

Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.

What Skills Provide

Specialized workflows - Multi-step procedures for specific domains
Tool integrations - Instructions for working with specific file formats or APIs
Domain expertise - Company-specific knowledge, schemas, business logic
Bundled resources - Scripts, references, and assets for complex and repetitive tasks

Core Principles

Concise is Key

The context window is a public good. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
